Relates to a device. When the initial crystallization step is carried out by the irradiation light source 4 from the flash light source 7, by providing a means for lowering the light emission intensity to substantially zero level at a moment after the predetermined time light emission (blocking circuit section 10) Both large irradiating power and short irradiating time are made compatible, and various thermal damages are reduced. In this method, since the wasteful electric energy is not consumed, the completion time of charging electric energy for the next discharge light emission can be shortened. In addition, by providing means for maintaining a large difference between the applied voltage and the charging voltage (accumulating circuit section 8 and trigger circuit 9), the charging completion time can be further shortened and the processing speed of the initialization process can be increased. In particular, in the manufacturing process of the optical information recording member having a single plate configuration, by adding an annealing process in combination with the resin protective layer forming process or the recording thin film initialization process, The optical information recording medium having excellent servo characteristics can be obtained by reducing or correcting the warping and skewing of the medium due to the shrinkage of the resin layer and the recording thin film layer. As a constituent method of the optical information recording medium, by forming one of the two media to be bonded so as to transmit at least 3% or more of ultraviolet light, the ultraviolet curable resin can be made into an adhesive, and as a result, the manufacturing process can be simplified.
